It also cleans up the past: paste the link to any post or ad, load every comment on it, and clear the junk in bulk. Every plan includes every feature, all the pages your Facebook account manages and unlimited team members. Plans differ only in how many comments a month they cover.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

CommentWatchDog's answer

CommentWatchDog was built by Anant Gupta, who runs Facebook and Instagram ads for his own companies, WhatChimp and GrowthToolkit, at close to $40,000 a month. Spam kept showing up under those ads and dragged down lead quality and return on ad spend, and cleaning it by hand every day did not hold. So he built a tool that reads every comment as it lands and hides or deletes what he would have taken down himself. It launched in 2026 and is made by GrowMeOrganic LLC.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
